Hey guys great idea, for the diff lock. Have to try this out on the 300.
Williebee, when we are going to leave the bike for any amount of time we usually turn the handlebars hard to one side. We then take a precut length of chain or cable and wrap it around the handlebars and rear rack on the same side then lock the two ends together with a padlock. Might not be the prettiest looking steering lock but works well and doesn't take much time to do. Some of the pre-made security cables 6 or 7 footers (depending on the bike) will do the job quite well.
